BELLA

Ultra silent hood thanks to Sil-K ACT technology.

Thanks to this innovative technological solution Pretty reduces by 13 decibels the noise level compared with a model not fitted with Silk Act. Once recorded the noise produced directly at its source, Silk Act creates a sound wave of the opposite shape that cancels out the original and thus eliminates the perception of noise. Moreover, a change of the acoustic frequency to lower tones makes the perceived noise less annoying.
